T 0 all whom it mayconcem l 3e it known that I, ALFRED D. T411", citizen of the United. States, and resident of Evanston, county of-Cook, and State of ed for the tran'sportation'of such 'lading as ores, coal, gravel,'etc.; andits object is to .provide a car for this service "which, while having great capacity, may be 'quickly and readily dumped;'will be free from the obj ectionable trap or dumping doors now." in common use;'-a further advantage-being that the body may be readily removed from'the framework of the car. for repairs or substitution. if

In its broader aspects the invention consists of a car having a body composed of two sections, the division being on the tran'sverse median line, each' section being pivoted at its inner end upon a rod or shaft mounted upon the upper portion of the framing, permitting its outer end to be raised for the purpose of discharging the lading. It consists further in various details of construction as hereinafter set forth, including means for tilting the body sections, for locking them in service position and in raised position.

The invention is illustrated in the accompanying drawings, in which Figure l is a side view of the car, partly in elevation, partly in section, some portions being broken away, differently raised positions of the body sectionsb in indicated in 'The underframing of the car comprises a pair of side'sills' lil, 11, sh own' as of channel section, anda c ter sill' 12, shown as an "I- beam.- These sills are; preferably"oifset between detracts, afshown'in stilt/able slid ti-T141 EIWSS "18,

14, 15, are provided as may be essential to strength and rigidity. The center sill, while shown as a single I-beam, may take any preferred form, it being deemed preferable, however, to give it the least practicable width n order to provide ample clearance for dumping. Furthermore, the end portions of the center sill will be suitably configured to accommodate the draft gear. This detail having no relation to theessential features of the invention, may be worked out by the builder according to his own j udgment and 1s not illustrated.

The upper framing of the car comprises a plurality of standards, as 16,17. and 18, ris mg from the sills, andside and end string ers 19, 20, secured to the upper ends thereof, th s framing being braced by diagonals, as 21', 22, The diagonals are shown as un ted at their upper ends to form an arch Wlllch springs from the downwardly 'inclined portions of the offset of the side sills, heretofore referred to. The upper framework may be further stiffened by means of uprights 23.

The body of the car comprises a pair of buckets 24, 25, which are oblong rectangular in horizontal section and meet at the transverse median line of the car, their adjacent ends being open. Each bucket comprises side walls 26, 27, and end wall 28, and a bottom 29. The outer end of the bucket is of less depth than the inner end, the latter portion fitting within the downwardly otl'set portion of the sills. The inner portion of the bottom of the bucket is channeled, as

-shown at 30, to accommodate an A-shaped deflecting plate 31 covering the center sill 12. A pair of channel bars 32, 33, are socured to the under face of the bottom 29, and may be continued upwardly along the outer face of the end 28. "These bars not only stiffen the'bucket but serve as retainers for the hoisting chains or cables hereinafter described. The bucket is further reinforced by a rail in the form of an angle bar 34:, secured to its upper margin.

To each of the upper inner corners of each bucket tliere'is securedan eye plate 35, 36, adapted to receive a shaft 37, the ends of which rest loosely within suitable pockets" in the form of chains, are attached-tome inner ends of the bottoms of the bucketa as shown the attachment being" to the chan nel bars 32, 33. These cables extend to y n:d.=- the end of the car, below the bucket and a upwardlyaoyer, a shaft 01: roller $1,; jour: n'aled" in mater-her uprights of the car frame, and thence downwardly to a windingshaft 4:2, similarly journaled, to which shaft they are firmly. secured. 7 The shaft 42 carriesja '\VO II11 gear 43, meshing with aworm for'med on a'short sliaft45,'"journaled in abra'cket"46 secured to the end} frame 'of'theear, such attachment, in theconstru'ction' as illustrated, being to the uprights- 23,23. The projecting end of the shaft 456s squared for the engagement of a wrench=or suitable crank by means of which it may be turned: f j

" hen the buckets 2d, 25, are in service position the-margins of their inner 'ends abut, thereby forming a single commodious receptacle for the lading, the Weight of which urges the two buckets together and prevents leakage. The outstanding leaf of the angle bar 34 rests upon theside and end stringers 19, 20, and the bottom of'the'"bucket rests upon a cross beam of the subframe,' which may be the body bolsterof the car. 'When itis desired to clump the'load the buckets are tilted upwardly, as-indicated by dotted lines in Fig '1, by turning-the 'shaft45 or by -the application of lifting power in-any other way. While hoisting mechanism incorporated vinto the car is shown,;itwill, of course, be entirely feasible to tilt the buckets by means of a crane placed at the-side of the track.-

Should itibe desired to remove the body of the car from-the framing, either while full or'empty, it -may be accomplished by connecting suitable hoisting mechanism to the shaft 37. Inasmuch as the cars used upon any road Will' ordinarily be of uniform construction, a defective body may be replaced by another in order that the car may not go'out of service while repairs, are being made. 1 :1

- If deemed advisable a 'lockmay be provided for holding the'buckets in'service position to prevent themfrom" being jarred apart in transit. .Such a locking device is shown as comprising a hook-47, pivotally attached'to the end of the-car frame and adapted to turnover the end ofthe bucket. Means may also be provided for holding the buckets in elevated positioir-j-For that purpose there is shown. a-segmental ratchet bar 48, attached vto the side frames of the car, and aweighted pawl 49' attached to the outer ;face ,of the sidewall of the; bucket for engaging the. teeth of the ratchet. .when the is Y 1 i I '7 A practical embodiment of the invention is shown and described, but various changes in detail may be made without departing fwmt QQee I clanii 'as my 1nvent1on -;1; In a dump car, in combination, a suit able frame, a body loosely supported in the -.v frame;and divided on a vertical plane into two sections, the two sections being pivoted to the frame onacommon center adjacent the upper portion of their meeting edges.
